I've built a gauge that I can have attached the the transmission while driving down the road to test pressures at shift points. I just need to get my car back as my brother has been borrowing it for the past few weeks. Thinking more about this, it's a warm condition as kmomotaro has reiterated. Things that happen when the overall temperature of the car is warmer is that the transmission fluid is thinner, the ECT sensor sends a lower resistance to the ECM, seals soften up and become more pliable. Resistance in wires increases (even if minimal it's still a suspect. Components expand. Just food for thought to maybe provoke an idea?
